IFN-gamma signature-driven neoadjuvant domatinostat, nivolumab and ipilimumab in stage III melanoma – the DONIMI trial

Project description:Low baseline Interferon gamma (IFNg) response signature is associated with lack of response to neo-adjuvant anti-PD1 + anti-CTLA4 therapy in patients with melanoma. Domatinostat, a class I specific histone deacetylase inhibitor is known to induce IFNg response in patients with advanced stage melanoma. Thus, addition of domatinostat to anti-PD1 + anti-CTLA4 might result in increased response to treatment. However, the effect of this combination therapy on tumor growth has not been evaluated in the pre-clinical setting. We therefore evaluated whether addition of domatinostat results in immune modulation and tumor growth control in the MeVa2.1.dOVA murine melanoma model. We provide pre-clinical evidence to use this combination in melanoma patients.

Pilot Trial of Arginine Deprivation plus Nivolumab and Ipilimumab in Patients with Metastatic Uveal Melanoma

Project description:Metastatic uveal melanoma (UM) remains challenging to treat, with objective response rates to immune checkpoint blockade (ICB) much lower than in primary cutaneous melanoma (CM). Besides a lower mutational burden, the overall immune-excluded tumor microenvironment of UM might contribute to the poor response rate. We therefore aimed at targeting deficiency in argininosuccinate synthase 1, which is a key metabolic feature of UM. This study aimed at investigating safety and tolerability of a triple combination consisting of ipilimumab and nivolumab immunotherapy and the metabolic therapy ADI-PEG 20. 9 patients were enrolled in this pilot study. The combination therapy was safe and tolerable with absence of immune related adverse events (irAE) of special interest but with 4 of 9 patients experiencing a CTCAE grade 3 AE. No objective responses were observed. All except one patient developed anti-drug antibodies (ADA) within a month of treatment initiation and therefore did not maintain arginine depletion. Further, an IFNg-dependent inflammatory signature was observed in metastatic lesions in patients pre-treated with ICB compared with patients with no pretreatment. Multiplex immunohistochemistry demonstrated variable presence of tumor infiltrating CD8 lymphocytes and PD-L1 expression at baseline in metastases.

Immunomodulatory response to neoadjuvant nivolumab in non-metastatic clear cell renal cell carcinoma

Project description:Novel perioperative strategies are needed to reduce recurrence rates in patients undergoing nephrectomy for high-risk, non-metastatic clear cell renal cell carcinoma (ccRCC). We conducted a prospective, phase I trial of neoadjuvant nivolumab prior to nephrectomy in 15 evaluable patients with non-metastatic ccRCC. We leveraged tissue from that cohort to elucidate the effects of PD-1 inhibition on immune cell populations in ccRCC and correlate the evolving immune milieu with anti-PD-1 response. We found that nivolumab durably induces a pro-inflammatory state within the primary tumor, and baseline immune infiltration within the primary tumor correlates with nivolumab responsiveness. Nivolumab increases CTLA-4 expression in the primary tumor, and subsequent nephrectomy increases circulating concentrations of sPD-L1, sPD-L3 (sB7-H3), and s4-1BB. These findings form the basis to consider neoadjuvant immune checkpoint inhibition (ICI) for high-risk ccRCC while the tumor remains in situ and provide the rationale for perioperative strategies of novel ICI combinations.

Biopsies from advanced melanoma before and/or after treatment with nivolumab

Project description:Expression profiling of tumor samples obtained during CA209-038 (ClinicalTrials.gov Identifier: NCT01621490). The purpose of this study is to evaluate pharmacodynamic changes of nivolumab and nivolumab in combination with ipilimumab treatment on the biomarkers measured in the peripheral blood and tumor tissues of subjects with advanced melanoma (unresectable or advanced). Samples are rumor core needle biopsies obtained at trial enrolment (i.e. Screen) and/or at Cycle 1 Day 29 (i.e.Week 4) from Subjects With Advanced Melanoma (Unresectable or Metastatic) treated with nivolumab (BMS-936558,MDX-1106) 3 mg/kg solution intravenously every 2 weeks on Bristol-Myers Squibb clinical trial protocol CA209-038 Part 1 . Cohort 2 patients have progressed on anti-CTLA4 (ipilimumab) monoclonal antibody therapy. Values are from an interim lock of the trial data in July 2014. Best overall response (BOR) was defined using RECIST 1.1 criteria: tumor assessments between date of first dose and the date of first objectively documented progression, or the date of non-missing subsequent anti-cancer therapy (whichever occurs first) were used to derive BOR. MPCT is Maximum reduction in tumor size (index lesions only) up to first progression, and is the value typically shown on a waterfall plot.

Neoadjuvant immune checkpoint blockade in retroperitoneal dedifferentiated liposarcoma and extremity/trunk undifferentiated pleomorphic sarcoma (NCT03307616)

Project description:Recent evidence suggests that immune checkpoint blockade (ICB) has some activity in metastatic dedifferentiated liposarcoma (DDLPS) and undifferentiated pleomorphic sarcoma (UPS). We conducted a randomized, non-comparative phase 2 trial (NCT03307616) of nivolumab or nivolumab/ipilimumab in patients with resectable retroperitoneal DDLPS (n=17) and extremity/truncal UPS (n=10), with UPS patients receiving concurrent radiation therapy. The primary endpoint of pathologic response as assessed by percent hyalinization was observed to be a median of 8.8% in DDLPS patients and 89% in UPS patients and similar in nivolumab and ipilimumab/nivolumab arms in both cohorts . Higher intratumoral densities of T-regulatory cells were associated with absence of pathologic response (hyalinization<30%). Tumor infiltration by B-cells was associated with higher densities of T-regulatory cells before treatment; this association was lost upon ICB treatment. Our data demonstrate that neoadjuvant ICB with concurrent radiation may have significant efficacy in UPS and is associated complex immune changes in the tumor microenvironment in DDLPS and UPS.

PRADO trial - Personalized response-directed surgery and adjuvant therapy after neoadjuvant ipilimumab plus nivolumab in stage III melanoma

Project description:The PRADO trial tested a personalized response-directed treatment approach based on the pathologic response after neoadjuvant ipilimumab plus nivolumab in stage III melanoma patients. In patients achieving a major pathologic response, in their index lymph node (the largest lymph node metastasis at baseline), therapeutic lymph node dissection (TLND) and adjuvant therapy were omitted. Patients with partial response underwent TLND only, whereas patients with pathologic non-response underwent TLND and adjuvant systemic therapy Ã‚Â± synchronous radiotherapy. Biomarker analyses based on baseline RNA sequencing data were performed in order to find features that are associated with major pathologic response.
